Answer:
x = -20
Step-by-step explanation:
3/4x-5=x
Subtract 3/4x from each side
3/4x - 3/4x -5=x-3/4x
3/4x - 3/4x -5=4/4x-3/4x
-5 = 1/4x
Multiply each side by 4
4 * -5 = 1/4x * 4
-20 =x
Answer:
f(x) – g(x) = x^2 - 4x + 3
Step-by-step explanation:
f(x) = 3x^2 - 4x + 5 and g(x) = 2x^2 + 2,
f(x) – g(x) = 3x^2 - 4x + 5 - ( 2x^2 + 2)
Distribute the minus sign
f(x) – g(x) = 3x^2 - 4x + 5 - 2x^2 - 2
Combine like terms
f(x) – g(x) = x^2 - 4x + 3
Answer:
Which number lies halfway between:
